These surveys of 8th- and 10th-grade students are part of a series that explores changes in important values, behaviors, and lifestyle orientations of contemporary American youth. Students in each grade are randomly assigned to complete one of four questionnaires, each with a different subset of topical questions but containing a set of "core" questions on demographics and drug use. There are about 450 variables across the questionnaires. Drugs covered by this survey include amphetamines (stimulants), barbiturates (tranquilizers), other prescription drugs, tobacco, alcohol, inhalants, steroids, marijuana, hashish, LSD, hallucinogens, cocaine, crack, and injection drugs such as heroin.

Multistage area probability sample design involving three selection stages: (1) geographic areas or primary sampling units (PSUs), (2) schools (or linked groups of schools) within PSUs, and (3) students within sampled schools. Of the 72 PSUs, 8 were selected with certainty, 10 were selected with a probability of .50, and the remainder were selected with probability proportionate to the size of the 8th- or 10th- grade class. In schools with more than 350 students in the grade, a random sample of students or classes was drawn. In schools with less than 350 students in a grade, all students were asked to participate. Each school was asked to participate for two years so that each year one-half of the sample is replaced. Schools refusing participation were replaced with similar schools in terms of geographic location, size, and type of school (e.g., public, private/Catholic, private/non-Catholic). For the 8th-grade survey, schools with less than 20 8th graders were excluded from the sample. For the 10th-grade survey, schools with less than 25 10th graders were excluded. The participation rate among schools has been between 66 and 80 percent since the inception of the study. self-administered questionnaires 2003 2003

ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Standardized missing values.
  • Created online analysis version with question text.
  • Checked for undocumented or out-of-range codes.
The student response rates for the 2003 8th- and 10th-grade surveys were 89 percent and 88 percent, respectively. ICPSR

National Institute on Drug Abuse 2010-08-10 ICPSR 2010-08-10 Corrected data were provided by the PI for the question asking about binge drinking (item reference number 00850). Other minor corrections were made to the question text and value labels to provide greater consistency between matching variables in other years of data in the series. 2006-03-30 ICPSR 2006-03-30 File UG4018.ALL.PDF was removed from any previous datasets and flagged as a study-level file, so that it will accompany all downloads. 2005-11-04 ICPSR 2005-11-04 On 2005-03-14 new files were added to one or more datasets. These files included additional setup files as well as one or more of the following: SAS program, SAS transport, SPSS portable, and Stata system files. The metadata record was revised 2005-11-04 to reflect these additions. StudyUnit04018

To protect the anonymity of respondents, all variables that could be used to identify individuals have been collapsed or recoded in the public use files. These modifications should not affect analytic uses of the public use files.
StudyUnit04018
Variables omitted from the Western region questionnaires are noted in each codebook.
StudyUnit04018
Frequency and percentage distributions displayed in the codebooks are unweighted, rather than weighted by variable V5 as they had been in previous years. This change was made to simplify both the production of the codebooks and their interpretation by the analyst.
